Why Choose the ABB XRG1-50/5-3P Switch Disconnector Fuse?
The ABB XRG1-50/5-3P (1SEP204481R1500) is a high-performance three-pole switch disconnector fuse designed for safe switching, isolation and circuit protection in low-voltage electrical distribution systems. As part of the advanced ABB SlimLine XR Gold series, it combines dependable operation with a compact busbar-mounted design for demanding industrial and commercial installations.
This switch disconnector fuse is engineered for installation on busbar systems with a 50 mm phase distance and 5 mm busbar thickness. Its wire-free mounting arrangement helps reduce installation time, simplify switchboard construction and provide an efficient connection to the distribution busbar system.
With a rated operational current of 250 A, a rated operational voltage of 690 V AC and compatibility with NH1 DIN fuse links, the XRG1-50/5-3P is suitable for protecting feeders, machinery and electrical distribution circuits. Its manual operating mechanism and true-position indication support reliable isolation and improved operator safety.

Efficient Protection for Busbar Distribution Systems
Switch disconnector fuses combine manual electrical isolation with the overload and short-circuit protection provided by replaceable fuse links. This allows circuits to be safely disconnected during maintenance while helping protect cables, equipment and downstream electrical loads against damaging fault currents.
The ABB SlimLine XR Gold series is designed for efficient installation directly onto compatible busbar systems. Its true-position indication helps operators confirm whether the contacts are open or closed, while the robust construction supports reliable performance in industrial switchboards and power distribution equipment.
Typical Applications
- Industrial low-voltage switchboards.
- Busbar power distribution systems.
- Main and sub-distribution panels.
- Incoming and outgoing feeder protection.
- Manufacturing and processing equipment.
- Commercial and infrastructure electrical installations.
